Railing for Bunkhouse top

My bunk house area has an accordion door that closed it and the bathroom off from the rest of the trailer. The door was attached to the cabinetry between the refrigerator and a closet. A plastic peg was screwed to the edge of the wall separating the bunkhouse and dinette. It was used to secure the door when closed. When opened there was a limited amount of room to go through the doorway. I kept scrapping my side and tearing t-shirts on the plastic peg. I attached an oak 1 x 2 flat against the bunk edges in the corner where the bunks and the dinette and bunkhouse wall meet. The oak 1 x 2 goes from the floor to the ceiling. I took the accordion door down and reattached it to the Oak 1 x 2 and moved the plastic peg to where the door used to be mounted. This let me have almost 6 more inches of opening. The door is now behind the wall and the peg is no longer exposed tearing my shirts.

A secondary benefit was it allowed me to use some 8 x 48 plywood scraps I had that I could shove between the bathroom wall and the bunk mattresses standing on edge. I can slide them over across the opening to the bunks to keep things from sliding off the mattresses while I'm driving down the road. The mattresses keep the plywood scraps in place and the Oak 1 x 2 keeps the plywood from slipping off the bunk platform. This can also keep a kid from falling out of the bunk. You might think about adding a 1 x 2 and some plywood like I did. All you would have to do is sand and paint or urethane the plywood.
